When Can I Be Personally Sued as a Director or Shareholder?

What limited liability actually protects

A corporation is a separate legal person, distinct from the shareholders who own it and the directors who run it. That separation is the whole point of incorporating: ordinarily, a corporation’s creditors can pursue the corporation’s assets but not the personal assets of the people behind it. Courts will set that shield aside, a doctrine known as “piercing the corporate veil,” only in narrow circumstances: where the corporation was completely dominated and controlled by an individual and used as a vehicle for fraud or improper conduct, as set out in Transamerica Life Insurance Co. of Canada v Canada Life Assurance Co. This is a common-law principle, not a provincial statute, so it applies the same way federally and in both Ontario and Alberta.

Beyond veil-piercing, every Canadian corporate statute carves out specific, defined situations where directors (not shareholders generally) become personally responsible for particular debts. Those carve-outs are where most real personal-liability exposure comes from.

Unpaid wages: directors can be sued directly

Under section 119(1) of the Canada Business Corporations Act, directors of a federally incorporated company are jointly and severally liable to employees for up to six months’ unpaid wages for services performed while they held office. That exposure is time-limited: a director cannot be held liable unless sued while still a director or within two years after ceasing to be one, under CBCA section 119(3).

Ontario’s Business Corporations Act imposes the same type of personal liability on directors of Ontario-incorporated companies, confirmed under sections 130 and 131, per Ontario’s Ministry of Public and Business Service Delivery. Alberta’s Business Corporations Act contains a mirrored, dedicated provision titled “Directors’ liability for wages” at ABCA section 119.

Ontario employees also have a separate, faster route through employment standards law. Under section 81 of the Employment Standards Act, 2000, a director can be personally ordered to pay unpaid wages once specific trigger events occur, such as an unpaid Ministry order or an unsatisfied claim filed with a receiver or trustee in bankruptcy. The Ministry does not have to fully exhaust collection against the corporation first: ESA section 81(2) confirms that proceedings against a director can begin without first exhausting proceedings against the employer.

Unremitted taxes: source deductions and GST/HST

Tax debts are the other major exception to the corporate shield, and this rule applies identically across Ontario, Alberta, and the rest of Canada because it comes from federal tax statutes. Under section 227.1(1) of the Income Tax Act, directors become personally liable when a corporation fails to deduct, withhold, or remit income tax source deductions from employees’ pay. The same exposure exists for sales tax: under section 323(1) of the Excise Tax Act, directors are jointly and severally liable when a corporation fails to remit GST/HST net tax.

Both liabilities have limits built in. The CRA’s Information Circular IC89-2R confirms that a director can avoid liability by demonstrating due diligence to prevent the failure, that the CRA must first show it cannot recover the amount from the corporation itself, and that any assessment against a former director must happen within two years of them ceasing to hold that role.

Alberta’s unlimited liability corporations: a different rule for shareholders

Everything above targets directors, not shareholders as such; a shareholder who is not also a director is not personally on the hook for these wage and tax debts. Alberta is the exception to that exception. Alberta uniquely permits incorporation as an Unlimited Liability Corporation (ULC), and under ABCA section 15.3, the ULC’s incorporating documents must expressly state that shareholders’ liability for the corporation’s debts is unlimited and joint and several. That liability sticks even if the corporation fails to properly maintain its ULC status or otherwise comply with the related filing requirements, since the ABCA’s ULC provisions state that a shareholder’s liability is unaffected by the corporation’s own non-compliance. Outside a ULC structure, shareholders in Ontario, Alberta, and federally keep the standard limited-liability protection.

Reducing the exposure: insurance and indemnification

Corporations Canada confirms that beyond these statutory triggers, directors and officers can face personal liability for unpaid wages and unremitted source deductions, and points to director and officer (D&O) liability insurance and corporate indemnification agreements as the standard tools used to manage that exposure. Neither eliminates the underlying statutory liability itself; both shift who ultimately pays if a claim against a director succeeds.
